TA Spoiler w/out center supports...PICS!!!

Well, since i have an extra highrise TA spoiler i have decided to get a little creative with it and remove the center supports. here are some pics showing what i hope the finish product will look like:

w/supports:

w/out supports:

progress pics of my spoiler:

here are a few more. the support that is on the driver's side has been smoothed like the rest of the underside of the spoiler. got started on the passenger support but called it a day.

the spoiler is still sturdy and i highly doubt once completed that it will sag...

just got some more sandpaper to continue the process. after i get the area prepped, i need to see what exactly will bond to the spoiler so that it holds. i have fiberglass to use right now. if there was a way to take the top of the spoiler off so i could work from the inside out would make it so much easier, but i dont think i can do that.

is the whole inside if the spoiler hollow? would there be any way to strengthen the middle section from the inside so it is more sturdy without the center supports?

yes it is hollow. it 2-pieces glued/laminated together. if i can separate them to work from the 'inside-out' then, that would be ideal, but i dont think it will play into my favor...

im looking into that. i have both supports sanded down flush now. i have some fiberglass that i hope to use...

i need to research what will bond to the composite polymeyer plastic spoiler. im not 100% sure if fiberglass resin will be the most effective. if i need to fill the hole, i can always find out exactly the material of the spoiler and find something to match it and build up from there with fiberglass and then bondo the low areas, prime, sand paint, etc...

this will be very interesting, best of luck you to. You know if this turns out well... you should test your skills in being the first to put a TA hatch spoiler on a convertible trunk. It would take serious amounts of work though. Its been tried but didn't work out very well.

If you want the fiberglass resin to stick, try not to have the area around the hole smooth. Use like a 36 grit sandpaper to leave a really rough edge with deep scratches into it. This way the resin falls into the deep scratches and will hold onto the material better.

indeed... way off in the distant future like maybe the last thing I ever do if I have money lying around for some reason is buy some spare parts and go to a shop and have them make me one... I think you would have to change the hinges to to clear a taller spoiler...

im using 40-grit to remove everything down to the white plastic. ive gone inside and scuffed up the underside of the openings. now i could take my dremel and 'score' grooves and roughin up the area as well. I'm using woven fiblerglass for a stronger bond, but realize that fiberglass itself is not a 'structural' material. I figure I could cut it into 2" strips and overlap 1" until covering the hole completely and the do 2 more layers (perpendicualr and then 45°) to ensure a good bond. then sand down and use bondo to smooth all the imperfections and then complete whats left.

only concern with using some sort of expanding foam for additional rigidness is the fact too much could split to spoiler. doing it before patching allows for better control, but doing it after patching, risks cracking the work and possiblely plugging the drain holes that are in the side/outer supports. IMO, the spoiler is still rigid enough and still holds its shape just fine.
